The US maintains tax treaties with 67+ countries, and non-resident aliens need an ITIN for non-residentsto claim these benefits. Without an ITIN, the IRS applies 30% default withholding on all US-sourced income under IRC 1441. An ITIN lets you file Form 1040-NR, deduct business expenses, and reduce withholding to 0-15% depending on your country's treaty. itin.so processes applications for $197 (standard) or $297 (express), with IRS approval in 6 to 11 weeks.

Quick answer

Non-resident aliens need an ITIN to claim US tax treaty benefits with 67+ countries and avoid the default 30% IRS withholding on US-sourced income. An ITIN lets you file Form 1040-NR and reduce withholding to 0-15%. itin.so processes applications for $197-$297.

Who Counts as a Non-Resident Alien for ITIN Purposes?

The IRS classifies you as a non-resident alien (NRA) under IRC 7701(b) if you are not a US citizen and do not meet the green card test or the substantial presence test. The substantial presence test counts physical presence: 31+ days in the current year AND 183+ days using the weighted 3-year formula.

Common Non-Residents Who Need ITINs

Foreign nationals owning US rental property (FIRPTA, Section 871(d))
International freelancers and contractors working for US clients
Amazon sellers and e-commerce operators on US platforms
Foreign investors receiving dividends or interest from US sources
Non-resident spouses filing jointly with US citizen spouses
International students with taxable income

The Substantial Presence Test Formula

Days in current year + (1/3 of prior year days) + (1/6 of second prior year days). If the total is 183+ AND you were in the US 31+ days this year, the IRS considers you a resident alien. Below 183 = non-resident alien status, requiring Form 1040-NR filing with your ITIN.

What Types of US Income Require an ITIN for Non-Residents?

2 categories of taxable income for NRAs, each with different tax treatment:

Effectively Connected Income (ECI)

Income from a US trade or business: Amazon sales, freelance work, LLC operations, and rental property (with Section 871(d) election). Taxed at graduated rates (10% to 37%) with full business expense deductions allowed. This is the most common income type for Amazon sellers and freelancers.

FDAP Income (Fixed, Determinable, Annual, Periodic)

Passive income: dividends, interest, rents (without 871(d) election), royalties. Taxed at a flat 30% or reduced treaty rate. No deductions allowed. The withholding agent (bank, broker, tenant) collects tax before paying you.

Real Property Income

US real estate rental income can be treated as ECI under Section 871(d), allowing deductions for mortgage interest, property taxes, insurance, repairs, and depreciation over 27.5 years. Without this election, gross rent faces 30% flat withholding. See our real estate investor ITIN guide.

How Do Tax Treaties Reduce Withholding for Non-Residents?

The US has income tax treaties with 67+ countries. These treaties reduce or eliminate the 30% default withholding rate on specific income types. You need an ITIN to claim treaty benefits on Form 1040-NR with Form 8833.

Country	Business Income Rate	Dividend Rate	Interest Rate
United Kingdom	0%	15%	0%
Canada	0%	15%	10%
India	0%	25%	15%
Germany	0%	15%	0%
China	0%	10%	10%
No Treaty	30%	30%	30%

What Are the Tax Obligations for Non-Resident Aliens?

4 obligations for NRAs with US income:

File Form 1040-NR annually. Report all US-sourced income, claim deductions and treaty benefits, calculate actual tax liability. Deadline: June 15 (automatic extension for NRAs with no US wages), extendable to October 15 via Form 4868.
Submit W-8BEN to withholding agents. Every US entity paying you needs a W-8BEN on file to apply the correct withholding rate. Your ITIN goes on Line 5.
Maintain your ITIN. ITINs expire after 3 consecutive years of non-use per the PATH Act of 2015. File regularly to keep it active. See our ITIN expiration guide and renewal guide.
Report foreign-owned LLCs. If you own a US LLC, file Form 5472 + pro forma Form 1120 per IRC 6038A. $25,000 penalty per year for non-filing. See ITIN for LLC owners.

Frequently Asked Questions About ITIN for Non-Residents

What is an ITIN for non-residents?

An ITIN is a nine-digit tax processing number issued by the IRS under IRC 6109 to individuals who are not eligible for a Social Security Number but have a US tax filing obligation. Non-resident aliens use ITINs to file Form 1040-NR, claim tax treaty benefits from 67+ countries, and reduce withholding on US-sourced income from the default 30% rate.

Do all non-residents need an ITIN?

No. You need an ITIN only if you have a US tax filing obligation or need a US taxpayer ID for a valid reason. Common triggers include earning rental income from US property, freelance payments from US clients, Amazon or e-commerce sales, investment dividends, or being claimed as a dependent on someone's US return.

How do non-residents apply for an ITIN from outside the US?

Complete IRS Form W-7, attach a valid passport (satisfies both identity and foreign status per IRS Publication 1915), and include Form 1040-NR. Mail to the IRS ITIN Operation Center in Austin, Texas, or work with a Certifying Acceptance Agent like itin.so ($197 standard, $297 express) who verifies documents remotely.

Do I need a US address to get an ITIN?

No. You can use a foreign address on Form W-7. Line 2 accepts your foreign residential address and line 3 accepts a separate foreign mailing address if your post goes somewhere else. You do not need a US address, a US phone number, or a US visit to apply. The IRS mails your CP565 assignment notice to the mailing address on the form, wherever in the world that is, so make sure it is one you can reliably receive post at over the 6-11 week processing window.

What documents do non-residents need for an ITIN application?

A valid passport satisfies both identity and foreign status requirements in a single document. Without a passport, provide 2 of the 13 IRS-accepted documents: national ID card, birth certificate, foreign voter registration card, US visa, driver's license, or foreign military ID. All must be originals or certified copies.

How long does it take for a non-resident to get an ITIN?

The IRS processes ITIN applications in 6 to 11 weeks when submitted by mail. Processing times increase during peak tax season (January through April). Using a CAA like itin.so reduces rejection risk because documents are pre-verified before submission to the IRS.

Can a non-resident get an ITIN without filing a tax return?

In limited cases, yes. IRS exceptions apply if you need an ITIN for treaty benefits on passive income (dividends, interest), to complete a W-8BEN for a financial institution, or for third-party information return reporting. Each exception requires specific documentation listed in Form W-7 instructions.

What is the substantial presence test for non-resident status?

The IRS uses the substantial presence test under IRC 7701(b) to determine residency. You are a non-resident alien if you were present in the US fewer than 31 days in the current year, or fewer than 183 days using the weighted formula: current year days + 1/3 of prior year days + 1/6 of second prior year days.

What income types require an ITIN for non-residents?

Two categories: Effectively Connected Income (ECI) from US trade or business taxed at graduated rates, and FDAP income (fixed, determinable, annual, periodic) like dividends, interest, rents, and royalties taxed at a flat 30% or reduced treaty rate. Both require Form 1040-NR filing with your ITIN.

Do ITINs expire for non-residents?

Yes. ITINs expire if not used on a US federal tax return for 3 consecutive years per the PATH Act of 2015. ITINs with middle digits 70-88 have already expired and must be renewed via Form W-7 before use. File regularly to keep your ITIN active and avoid the renewal process.

How much does an ITIN cost for non-residents?

The IRS charges $0 for processing. itin.so charges $197 for standard service (7-10 business day W-7 preparation, email support) or $297 for express service (2-3 business day preparation, WhatsApp support, money-back guarantee). Both include CAA document verification and complete application review.
